1-way Hashing - Applications in DeFi (opens in new tab)

Trusting hardness of problems to keep your crpto safe It’s widely known that 1-way hash functions, particularly SHA-256, are the cornerstone of modern cryptography. What is a 1-way hash function? A 1-way hash function is a function H(x) where given H(x), finding a corresponding x (even if it’s not unique) is computationally infeasible, requiring brute force on the order of ~2^256 for SHA-256 Even finding a collision, i.e. two values $a \neq b$ such that $H(a) = H(b)$ takes ~2^128 attempts due...
